The Grand Vizier, in a last-ditch attempt to block Ibrahim's advance towards the capital. While Ibrahim commanded a force of 50,000 men, most of them were spread out along his supply lines from Cairo, and he had only 15,000 in Konya. Nevertheless, when the armies met on December 21, Ibrahim's forces won in a rout, capturing the Grand Vizier after he became lost in fog attempting to rally the collapsing left flank of his forces.
